The following is a daily text product issued by the OHRFC:Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
123 PM EDT Friday, May 17, 2013
Low pressure will approach the Ohio Valley from the southwest today. Moisture
ahead of the low will continue to lift north into the southern and western
portions of the basin today fueling scattered showers and isolated
thunderstorms. This pattern will continue for the next couple of days, though
activity will move from southwest to southeast as the low moves eastward
across the southern Ohio Valley.
By Monday the low will move off to the east and high pressure will build into
the basin. This will not keep the entire basin dry, but rains will be limited
and confined mainly to the edges of the basin. Chances of rain will increase
Tuesday as a front approaches from the west. The front is expected to move
through the basin around Wednesday of next week. Drier, more stable conditions
are expected behind the cold front.
...FLOOD POTENTIAL DISCUSSION...
No flooding is occurring at this time. While there are significant chances for
rain across the middle of the Ohio Valley through mid-next week, it is
expected to be scattered enough that additional river flooding is not
forecast. Some local or flash flooding is possible.
...24-HR OBSERVED PRECIPITATION USED IN TODAY'S RIVER FORECASTS...
Rain was generally oriented east-west across the basin through eastern
Illinois, the southern halves of Indiana and Ohio as well as northern Kentucky
and most of West Virginia. Basin averages were mostly 0.50 inch or less, but
a narrow axis from the southeast Illinois, across southern Indiana and across
northern Kentucky featured some basins with up to 2 inches of rainfall.
